| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Georgetown, TX | 37° | 96° | 35" | 0.0" |
| Chico, CA | 38° | 96° | 31" | 0.0" |

| Dublin, GA | 37° | 93° | 47" | 0.0" |
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value. Snow and frost-free days come from the nearest weather station, so neighbors often share them.
Warmer than it used to be
The last 30 years in Georgetown averaged 1.2° warmer than the 1900s. The biggest change is in February (+2.3°).
A smaller shift than in 60% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods. In a city of 107,000 people, part of the change is the city itself: pavement and buildings hold heat (the urban heat island).
